Story assisted mnemonic phrase

Abstract

Embodiments disclosed herein are related to generating and using a private key recovery seed based on random words extracted from a generated story to recover the private key. An input story is received from a user. The story includes random words and filler words that were previously generated. The number of random words generated is based on an entropy level. The random words included in the story are extracted. This means that the user does not need to enter any random words that are not included in the story to recover the private key. The random words are input into a first key recovery mechanism to thereby generate a private key recovery seed. The private key recovery seed is then input into a second private key recovery mechanism, the second private key recovery mechanism generating a recovered private key upon performing a recovery operation on the private key recovery seed.

Description

BACKGROUND[0001]Most of currently used documents or records that prove identity are issued by centralized organizations, such as governments, schools, employers, or other service centers or regulatory organizations. These organizations often maintain every member's identity in a centralized identity management system. A centralized identity management system is a centralized information system used for organizations to manage the issued identities, their authentication, authorization, roles and privileges. Centralized identity management systems have been deemed as secure since they often use professionally maintained hardware and software. Typically, the identity issuing organization sets the terms and requirements for registering people with the organization. Finally, when a party needs to verify another party's identity, the verifying party often needs to go through the centralized identity management system to obtain information verifying and / or authenticating the other party's ...

AI Technical Summary

Benefits of technology

The patent describes a method to recover a private key from a random word seed. The method uses a generated story that connects the random words in a way that's easy for the user to remember. This allows the user to enter the story into a recovery mechanism, which can extract the random words, generate the private key recovery seed, and recover the private key. This method prevents the random words from being easily copied and used by others, providing better security against theft, loss, or hostile misuse of the key.

Problems solved by technology

It is possible, however, that the DID owner may somehow lose the private key or at least lose control of the private key.

For example, the storage unit where the DID owner has stored the private key may be destroyed or lost.

Alternatively, the private key may be corrupted or become unusable for various reasons.

As will be appreciated, if the private key remains lost or unusable, the DID owner may not be able to use his or her DID or access any information related to the DID.
